What asset to choose to create a grid?

Hi,
Please tell me which asset from the store Unity will help me to create a game similar to a sea battle, but with certain features.
I need to create a 2D grid of cells, for example, the size of 10x10, on which the location of the ships in various forms are hidden from the player (their location is generated randomly).
And which asset can help with the introduction of various input methods for choosing which cell to shoot? (for example, select a cell with a mouse or send a command 1a or 3b)
Attached a picture for example.

Unity has built-in tilemap grids.

Yup, you may want to look into tilemaps.
